The GOP’s slow-motion fracture with Israel
Benjamin Netanyahu long ago lost the Democratic Party. Now he is losing the Republican base too, and the numbers are stark enough to suggest a structural realignment in American politics.
For decades, support for Israel was one of the few truly bipartisan pillars of U.S. foreign policy. That pillar is cracking. The latest Pew Research Center survey, fielded in late March 2026 about a month into the U.S.-Israeli war in Iran, found that 60% of Americans now hold an unfavorable view of Israel, up 7 points from last year and nearly 20 points since 2022. Among Democrats that figure hit 80%. But the shock is on the right.
The generation gap inside the GOP
Fifty-seven percent of Republicans under 50 now view Israel unfavorably, according to Pew, up from 50% in 2025. Among Republicans over 50, only about 24% share that negative view. That means roughly three in four older Republicans still carry the torch for the U.S.-Israel alliance, while a majority of their children and grandchildren have already let it go.
A separate New York Times-Siena College poll from May underscores the point: 55% of potential Republican voters ages 18 to 44 said they disapprove of Netanyahu’s leadership. Younger conservatives express skepticism about sending billions in U.S. aid to Israel and are increasingly receptive to arguments about outsized Israeli influence in Washington.
The Iran war broke the bond
The immediate catalyst is the war in Iran. Many conservatives, particularly in the grass-roots MAGA ecosystem, allege that Netanyahu arm-twisted President Trump into launching U.S. military strikes against Iran, a conflict that has dragged on longer than promised and spiked gas prices at home. That resentment has curdled into open suspicion.
Vice President JD Vance confronted the issue directly at a University of Mississippi town hall in October 2025. When a student asked whether Israel manipulates the White House, Vance replied: “When people say that Israel is somehow manipulating or controlling the president of the United States, they’re not controlling this president.”
The careful framing left the door open that previous presidents might have been controlled. For much of the Republican base, that hedge sounded like permission.
Cracks in Congress, casualties in primaries
The GOP-controlled Congress still broadly backs Israel, but the cracks are getting wider. The most visible casualty was Representative Thomas Massie of Kentucky, who was ousted in the May 2026 primary by Ed Gallrein, a Trump-endorsed challenger backed by pro-Israel PACs including the Republican Jewish Coalition. Massie was the only House Republican to vote against a resolution affirming Israel’s right to exist after October 7. His defeat sent a message: the party establishment will still punish anti-Israel apostasy.
But the establishment cannot punish everyone. Marjorie Taylor Greene, already a lame duck after announcing she would leave Congress, wrote that she could “no longer support the Republican Party” partly over the Israel question. Greene and Massie had jointly opposed legislation penalizing anti-Israel boycotts, arguing it infringed on American free speech. The fact that those positions once seemed fringe but now resonate with a generation of Republican voters is the real story.
Netanyahu’s shaky bet
Netanyahu has long staked his political survival on the alliance with Trump. He bet that a Republican White House would give Israel free rein in Gaza and against Iran. But the Iran war has soured Trump’s own party, and as the administration negotiates a ceasefire deal with Tehran, the prime minister is finding himself sidelined.
Netanyahu faces an election of his own in October 2026. He has floated the idea of ending U.S. military aid to Israel, a desperate gambit to reframe himself as independent from Washington. But as one Israeli journalist put it: “Netanyahu’s bet on Trump is looking a bit shaky.”
The distance between Trump and Netanyahu is growing. Trump’s team resents being dragged into an open-ended Middle Eastern war, and the president has shown he will apply leverage on Israel when it suits his political interests. The bipartisan consensus that once anchored the U.S.-Israel relationship is gone. What remains is a transactional alliance held together by habit, and habits can break faster than anyone expects.
